Ribose-taurine (Rib-T) suppressed the generation of inflammatory mediators and cytokines, such as nitric oxide (NO) and prostaglandin E2 (PGE2) through the inhibition of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expressions in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The production of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β induced by LPS was effectively blocked by Rib-T. Moreover, the anti-inflammatory actions of Rib-T were involved in its inhibitory effects against the nuclear translocation of nuclear factor-kappa B (NF-κB) p65, and NF-κB DNA-binding activity. These results suggest that the anti-inflammatory action of Rib-T is associated with NF-κB regulation.
